Application iled May 19,

To all whom it may concern.'

Be it known that I, ABRAHAM WATERMAN, a citizen of Russia, residin at Chicago, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Ventilated Garments, of which the following is a specification.

My invention relates to improvements and features of novelty in ventilated garments, such as raincoats, and concerns more particularly the construction of the seams provided with Ventilating structural characteristics. It is customary in garments of this style to supply means in some of the seams, such as those at the middle of the back and under the arms, with means for permitting a flow of air therethrough to prevent an ac-I cumulation of perspiration and to avoid undue heating of the wearer. This, of course, is required because of the moisture-proof or impervious character -of the material of which the garment is made.

The leading object of my invention is the provision of improved means for affording such ventilation and which at the same time will assure complete protection to the wearer from the entrance of rain to the interior of the garment. A further purpose of the invention is the production of such an efficient structure which is simple in construction, which is inconspicuous, which is 'effective in action, and which is inexpensive to produce.

In order that those skilled in this art may have a full and complete understanding of the invention from both structural and functional standpoints, I have illustrated two desirable embodiments of the same in the accompanying drawing forming a part of this specification and to which reference should be had in connection with the following detailed description. Throughout the views of this drawing like reference characters refer to the same parts.

In this drawing:

Figure 1 is a fragmentary elevation or face view of one of the ventilated seams with parts broken away or omitted to more clearly illustrate the construction.

Fig. 2 is a horizontal section on line 2 2 of Fig. 1.

Fig. 3 is a seam section on line 3 3 of Fig. 1 showing the eyeleted ventilation holes and indicating the seam opened up somewhat as will occur during movement of the Specification of Letters Patent.

wearer which causes the valves normally closing such apertures to temporarily open them.

Fig. i is a view similar to Fig. 1 of a somewhat modified construction.

1g. 5 is a horizontal cross section on line 5 5 of Fig. et and Fig. 6 is a lon 'tudinal or vertical section on line 6 6 of ig. 4.

Referring first to the species shown in Figs. l to 3, inclusive, it will be perceived that at the seam the two inner and outer fabric sections or pieces 10 and l1 respectively of the garment are slightly overlapped as illustrated most clearly in Fig. 2 and that the edge or marginal portion of the outer section is turned over inwardly at 12 and secured as by cementing or otherwise to the rear or inner face of such section to provide a finished edge. The material of which such parts 10` and ll is composed may be of any suitable character for the. purpose intended but, of course, would ordinarily be so made, as by rubberizing, as to be practically waterproof or impervious to moisture otherwise there would generally be no occasion for providing especially for ventilation.

Up to the points 13 and 14, the overlapped parts of the elements 10 and 11 are securely fastened together, preferably by cement-ing, to assure their perfect union, and between such points the fabric sections are not attached to one another except as indicated hereinafter.

The seam also includes an intermediate or supplementary waterproof or impermeable fabric strip 15 partially overlapping the rear faces of the two pieces 10 and 11 and cemented or otherwise secured around its entire margin to the back surfaces of such elements. This strip is fastened at its ends by such cementing to the main fabric parts 10 and l1 beyond or at the points 13 and 14 whereby the gap between such points is completely closed by the attached strip, thus preventing the passage of rain to the interior of the garment.

The interposed or intervening strip is supplied with a plurality of groups or sets of eyeletcd ventilation holes or apertures 16, 16, in the present instance comprising three spaced collections of two apertures each located in the central unattached part of such strip. Thus when these holes or valve ports are open the air can flow outwardly theretheir valves, the air at intervals is permittedV to escape through the seam from the interior of the garment, thus affording adequate ventilation. Rain, however, cannot pass inwardly through such seam because the ventilation apertures are adequately shielded'by their valve closures, and the latter are prol tected along their outer edges by underlying the margin oftherfabric piece 10. If any rain is driven between the parts 10 and 1l` it will iiow down and escape or be discharged between the same elements at the bottom ofV the intermediate strip. Y

To prevent undue-opening or gapping of the seam, the outer piece 1 1, 1f desired, may

i be tacked or secured to the underlying companion garment piece 10 at Points 19Y between the positions of the valve ports and valves.

Referring now to the other embodiment of the inventionshown in detail in Figs. Ll, 5 and 6, it will be seen that the adjacent fabric pieces 2O and 21 of the garment are not overlapped at the ventilated seam, but rather the margins of their contiguous edges are turned or folded back at 22 and cementedto their rear faces (shown in Fig. 5). These elements 20 and 2l are so positioned andsecured together that between the points 23 and 24 their finished edges just meet without overlap. An intermediate auxiliary waterproof strip 25 is located back of such open seam,'is cemented 'around itsentire periphery-to the back faces of the two garmentY pieces 20 and 21, and is supplied with three spaced groups or sets of two eyeleted ventilation apertures 2G, each collection hav- Y ing a fieXible waterproof fabric valve or cover 27 fastened along its upper edge only to the front face of the intermediate strip. To preserve a neat appearance and prevent undue opening of the seam the adjacent edges of the parts 20 and2l are desirably tacked or stitched between the valves and .their ventilation apertures to the underlyis prevented from passing through the holes 26 and in fiowing down is discharged or celivered between the fabric pieces 2O and 2l at the bottom of the intermediate strip 25, all as will be readily understood.

rl`hose skilled in this art will comprehend that thisinvention is not limited and restrict- Ved to the precise and exact details of construction illustrated and described since these maybe modified along more or less around its margin to the back faces of said pieces, and a fiexible water-proof unperforated valve covering said aperture andsecured along a portion only of. its margin to the front of said section, whereby the movements of the wearer of the garment intermittently effect the opening of said aperture.

2. A ventilated garment seam comprising in combination, a pair of adjacent waterproof garment pieces, an apertured otherwise-water-proof fabric section secured around its margin to the back faces of said pieces, and flexible water-proof unperforated valves covering said apertures and secured along ytheir top edges to the front of said section, whereby the movements of the wearer of the garment intermittently effect the opening of said apertures.

3. A ventilated garment seam comprising in co1nbination a `pair of adjacent vwaterproof garment pieces, a water-proof fabric section secured around its `margin to the back faces of said pieces and'having apern tures spaced apart lengthwise the seam, flexible water-proof valves covering said aperturesi and-'securedV along a portion only of theirv margins to the front` of said section, and means tacking said garment pieces together between said valves, whereby the movements Vof the wearer of the garment intermittently effect the opening of said apertures.

4. A. ventilated garment seam comprising in combination, a pair of water-proof garment pieces overlapped along their margins,

an apertured otherwise-water-proof fabric section secured around its'margin to the back faces of said pieces, and a flexible water-proof valve covering said aperture.y secured to the front ofV said section Valong its `top edge, and having a side edge beneaththe undermost of said garment pieces,

lengthwise the seam, flexible water-proof 10 valves covering said apertures, each valve being secured to the front of said section along its top edge and having a side edge beneath the undermost of said garment pieces7 and means tacking said pieces together between said valves.
